Eclipse中Ant执行JUnit测试的问题(1)

Eclipse 3.0.3 + Ant 1.6.2 + JUnit 3.8.1

构建配置文件build.xml:

<target name="junit">
    <junit>
        <formatter type="xml" />
        <batchtest todir="${report.dir}">
            <fileset dir="${classes.dir}" includes="**/*Test.class" />
        </batchtest>
    </junit>
</target>

在执行时出现了以下问题:

BUILD FAILED: build.xml:44: Could not create task or type of type: junit.

Ant could not find the task or a class this task relies upon.

This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
 - You have misspelt 'junit'.
   Fix: check your spelling.
 - The task needs an external JAR file to execute
     and this is not found at the right place in the classpath.
   Fix: check the documentation for dependencies.
   Fix: declare the task.
 - The task is an Ant optional task and the JAR file and/or libraries
     implementing the functionality were not found at the time you
     yourself built your installation of Ant from the Ant sources.
   Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
     task and make sure it contains more than merely a META-INF/MANIFEST.MF.
     If all it contains is the manifest, then rebuild Ant with the needed
     libraries present in ${ant.home}/lib/optional/, or alternatively,
     download a pre-built release version from apache.org
 - The build file was written for a later version of Ant
   Fix: upgrade to at least the latest release version of Ant
 - The task is not an Ant core or optional task
     and needs to be declared using <taskdef>.
 - You are attempting to use a task defined using
    <presetdef> or <macrodef> but have spelt wrong or not
   defined it at the point of use

Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath

Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.

产生上面错误的原因是Ant在执行junit任务时没有找到junit.jar这个文件。将junit.jar放到ANT_HOME/lib目录下,再次执行,这下该OK了吧!

有没有搞错,还产生同样的错误!到命令行下试试。打入命令ant junit,然后出现:

1
2
3
4
5
6
Buildfile: build.xml

junit:

BUILD SUCCESSFUL
Total time: 1 second

怎么会这样?命令行下可以,Eclipse中就不行了?

到Preferences -> Ant -> Runtime -> Classpath下设置一下junit.jar的路径,再次执行junit任务,终于在Console视图中看到了成功的消息。
